Nice tool with few flaws for pros It is a very nice tool set with a lot of features. Better than most on Android. Still no 1/f mode.on full res. Apparently the offset value isn't saved with the mic cal files, at least on my S6. Would also be very helpful if button selections were confirmed in the measurement window; like dBA, fast, slow, etc next to read out. Some confusion over some button states; I.e single vs 1/3 Oct Cal's. Font sizes still way too small on graphs for S6
Comprehensive audio app with great features Don't be without this brilliant audio tool on your Android. The waterfall is an excellent tool, for monitoring and setting up the audio spectrum level on your HiFi.
Met my expectations I use it with a Samsung Galaxy S7. This is just a no-brainer for $8. I used a BAFX BAFX3370 sound level meter to determine the calibration offset to be -9 dB for the internal microphone and -5 dB for the Dayton Audio iMM-6 measurement microphone on my device. The combination with or without the iMM-6 tracked very closely from about 40 dBA to 90 dBA SPL using a pink noise source and studio monitors. Under 40 dBA SPL they didn't track, and I wasn't able to provide a pink noise source above 90 dBA SPL.
The "musical note" when selected is in the brackets next to the displayed Hz. Maybe take more time than the 2 seconds your brain is only capable of and read the instructions... Still an Excellent app.
Did I ask for a refund? No, don't get too cute and cheeky with your customers; not good for biz. I am pointing out major flaws, and would like to see you fix those flaws I pointed to. I am reporting problems where we are supposed to and where Google wants us all to, here, in comments. Calibration is useless "Show Musical Notes" I dont see note names anywhere. If you mean Hz, that's Hertz, not musical notes.You have to deactivate tactile vib-on-press for key press in-app, all sounds and vibe must be off. Maybe put Cal Finish button on screen?
So much information Not just directly what is presented but what can be dirived with data analisys. This is a very serious and usefull app for any audio geek or professional.
